important to note the bull wheel 1, grain wheel 2, frame 3, steering truck 4:, seat 5, a

platform 6, elevator 7, bevel gear 8 on the driving connection for the elevator 7, guard fingers 9, sickle bar 10, driving connections 11 for the sickle bar, and grain board 13. It is also important to note the bearing bracket 14 on the frame 3, on which the ordinary reel is supported, and the driving connections from the bevel gear 8, including a bevel gear 15, for drivin an ordinary reel. The parts thus far described may be of the standard or any desired construction.

Referring now in detail to the improved harvester reel, the numeral 16 indicates an upright shaft having its lower end pivoted to the bearing bracket 14 for swinging movement in the direction of travel of the harvester. Mounted for sliding movement on the shaft 16 is a bearing bracket 17 having a pair of axially alined bearing hubs 18, in which is journaled a relatively short tubular driving shaft 19. This shaft 19 projects horizontally from the upri ht shaft 16, substantially vertically above t e sickle bar 10 and slightly beyond each of the hubs 1&5. Rigidly secured to the end of the shaft 19, adjacent to the shaft 16, is a crank arm 20. Also, rigidly secured to the driving shaft 19, between the shaft 16 and the crank arm 20, is a worm wheel 21. On the other end of the driving shaft 19 is rigidly secured a relatively large sprocket wheel 22.

A square shaft 23 extends parallel to the upright shaft 16 and is journaled, at its upper end, in a bearing 24, formed by extending the upper end of the shaft 16 laterally. The lower end of the shaft 23 is connected to a bevel gear 25 by a universal joint 26. The bevel gear 25 is journaled in a lateral extension of the bearing bracket 14 and meshes with the bevel gear 15. Slidably mounted on the shaft 23 is a worm 27, which meshes with the worm wheel 21 and is held for rotation with the shaft 23.

The worm 27 is held against endwise -movement with respect to the bearing shaft 19 of theim proved harvester reel is,

I in turn, driven from the elevator 7, through shaft 29 andsidelbarsSO constitute a frame for ,the improved .reel. The forward ends ofithe frame'bars .30 are bifurcated and have mounted therein slidingbearings .32, in which is journaled an idle fshaft 331.

Both' 'shafts 3.1 and 33 extend; parallel to the oscillatory shaft 29. "Chain tighteners 34, in the form of coiled springs, :are, compressed betweentheslidingbearings 32. and the transverse'fportions of the bifurcated ends of theyrrame bars 30.

Theshaftj'31is drivenfrom the driving shaft' 19flby asprocket chain 35, which runs over, the sprocket wheell'22 and-a. relatively small sprocketwheel 36;.keyed to said shaft 31; 'A' pair of laterally spaced sprocket chai'ns37 run over pairsof alined sprocket wh'e'elsf38, keyedto the. shafts 31 and .33. There is. one ,pair of. alined sprocketwheels 38 locatedon the, grain sideof each frame barIQZSOQ 'Aplurality o f;reel blades 39 are carried by the sprocket chains 37. As shown, these reel blades39arejformed from sheet metal with longitudinally spacedteeth 40 formed ontheiroIiteredgeS. Thebodies of 'thei'reel blades 39 and. theirflteeth 40 are corrugated fan'dqfl'anged to stifl'en and give the reelf. blades the, necessary strength. The reeljiblaides 39, are. secured to .the sprocket chains '37 by arms 41. formed. on certain of the 'links of said: sprocket chains. The arms 41 extend laterally outward from the sprocket, chains $37 and the reel blades 39 arelsecuredltoithe free end portionsthereof by nut-equipped bolts .42.

To give stability to the arms 41. andreducej thefmovements ,thereof, longitudinally of the sprocket chains 37, each thereofis provided with a u shaped foot 43. The

prongsqf-each foot are pivotally connected 55' to the respective arm 41fand; extend rearward therefrom, parallel to the respective sprocket chain '37, and thetransverse portionflofrsaid, foot. rests, on said. chain :37, as bestfshown in liligsfl6 and 7. Lugs .44, on the 4 1, engage the prongsjof the feet- 43 to fpreventdlifting movement thereof. The purpose of pivotally connecting .the feet 43 tothe, arms j4lisito permit the assembly of theflinks of the sprocket chains "37 with the linksof the arms 41.

The improved harvesterreel is raised and lowered on the shaft 16 and moved forward and backward in respect to the direction of thetravel of the harvester, by -a latch equipped primary hand lever 45 and a cooperating lock segment 46. The latch lever '45 extends horizontally and rcarwardly and is'inter'mediately fnlcrumed to the segment 46, atthe axisthereof, and its forward end is pivotally connected at 47 to the bearing bracket 17;; in a vertical planewand is; pivoted .-at .48to

The lock segmentJ46-extends the frame 3 for oscillatory movement ina vertical plane, in the direction of the travel of. the harvester. Obviously, when the primarylever-i45 is -locked to the locksegment' '46, the shaft 16 is rigidly locked. against pivotal movement. Bychangingthe interlockingengagement of the primary lever 45 with theiloeksegmentf46,.the shaft16 may beset in different oblique positions;

and. hence,,th e improved harvester. reel may be moved bodily, either forward or back-.

ward, .in respect to the direction of the travel ofxthe harvester. vO r, v by I releasing the primary lever 45 from the locksegment 46, andthen moving the freeendof the-said lever, either downward or vnpward, ,the reel may be raised or: loweredgbodily.

Oscillatory movement is imparted to the shaft 29, for .the :purpose of changing; the

horizontal inclination ofthe reel by a;sec-

ondary. latch-equipped ,hand; lever49- and cooperating. segment 50. The secondary' lever 49 extends vertically upwardvfromtheprt mary lever 45 and its lower end isfulcrumed thereon. The segment 50eis .in tee grally formed with .the ,primary. lever 45-. A relatively long, link 51 .aftordsaa connection between the intermediate portion of the secondary lever 49 and the crank arm 20.

Operation.

The operation of the improved harvester reel. may be briefly. stated as follows Continuous traveling movement ,is impartedto thegreel blades 39 from the .bevel gear15 of the harvesterthrough the several connections, previously identified. "llhe reel.

blades 39, during their lower -1 or operative run, :move :in substantially; a horizontal plane in the direction of the .arrow marked on Fig. 4. By actuating,:thesecondary lever49 to oscillate the frame bars 30,-'.t-he inclina" tionof thetravelingmovement of the operative run of the reel blades 39 may be changed, at, will. Or, by. settingthe primary lever 45 in different adjustments on. the

lock. segment 46, :the improved harvester.

reel may be advancedor.set backbodily. In case it is desired to elevate the reel bodily, .forathepnrpose of. clearing-a stone,

stump, or other obstruction, the primary lever .45 is. released :from the lockv segment 46 and its free end forced downward, thereby sliding the bearing bracket 17 upward on the shaft 16, which action raises the reel bodily. The reel may be held in this elevated position, until the obstruction is passed, and then return to its original position. Obviously, during this raising and lowering movement of the reel bodily, the inclination of the reel is not thrown out of adjustment, when the reel assumes its original position, for the reason that the secondary lever 49 is carried by the primary lever 45.

The horizontal traveling movement of the reel blades 39 prevent throwing the grain back and over the platform 6, or depositing the same on the rear of the platform. The improved reel will also pick up fallen and tangled grain and will not thresh, because it runs much slower than an ordinary reel with few blades. The improved reel, also, has a steady motion and does not have a beating action, as in an ordinary reel.

What I claim is l. A harvester reel, and means supporting the reel for compound vertical and horizontal adjustments, said means including a pivoted lock segment, a lever fulcrumed on the lock segment and a latch for securing the lever to the lock segment, whereby the lever may be held in different adjustments and the lock segment against pivotal movement.

2. A harvester reel, and means supporting the reel for compound vertical and horizontal adjustments, said mean's including a pivoted lock segment, a lever fulcrumed at the center of the lock segment and a latch for securing the lever to the lock segment, whereby the lever may be held in different adjustments and the lock segment against pivotal movement.

3. A harvester reel including a frame and traveling blades, and means supporting the reel frame for compound vertical and horizontal adjustments and for oscillation in a vertical plane, said means including a pivoted primary lock segment, a primary lever fulcrumed on the lock segment, a latch for securing the lever to the lock segment and a secondary lever and cooperating lock segment carried by the primary lever.

4. A harvester reel including a frame and traveling blades, and means supporting the reel frame for compound vertical and horizontal adjustments and for oscillation in a vertical plane, said means including a pivoted primary lock segment, a primary lever pivoted to the reel frame and fulcrumed on the primary lock segment, a latch for securing the primary lever to the primary lock segment, a secondary lever and cooperating lock segment carrie by the primary lever and a link connection between the secondary lever and reel frame.

5. Reel mechanism for harvesters comprising a frame mounted for bodily vertical and horizontal movements and for oscillatory movement in a vertical plane, blades mounted on the frame for substantially horizontal operative traveling movement, a primary lock segment pivotally mounted for vertical swinging movement, a primary lever fulcrumed at the center of the primary lock segment for imparting said vertical and horizontal movements to the frame, a secondary lock segment carried by the primary lever, and a secondary lever fulcrumed at the center of the secondary lock segment for imparting said oscillatory movement to the frame, said two levers having latches cooperating with the respective lock segments.

6. Reel mechanism for harvesters comprising an upright shaft mounted for swinging movement in the direction of travel of the harvester of which the reel mechanism is a part, a frame mounted on said shaft for raising and lowering movement and for oscillatory movement in a vertical plane, wheels journaled on said frame, belts arranged to run over said wheels, a plurality of laterally spaced reel blades carried by said belts, means for driving said belts, a primary lock segment pivotally mounted for vertical swinging movement, a primary lever fulcrumed at the center of said primary lock segment for raising and lowering said frame bodily and arranged to be locked to said lock segment for holding said shaft in different obli ue positions, a secondary lock segment carried by said primary lever, and a secondary lever fulcrumed at the center of said secondary lock segment for imparting oscillatory movement to the frame and arranged to be locked to said secondary lock segment for holding said frame in different oscillated positions.
